Description

[Technical Field]

[0001] The present invention relates to a hypoxic device for performing hypoxic therapy and / or hypoxic training, the device comprising a gas reservoir, a gas supply device, and a supply line suitable and designed for conducting a gas mixture from the gas reservoir to the gas supply device and / or a discharge line suitable and designed for conducting the gas mixture from the gas supply device to the gas reservoir. The present invention further relates to a method for performing hypoxic training, the method step of providing a hypoxic gas mixture and detecting a measurement signal with a CO2 sensor. [Background technology]

[0002] Hypoxia triggers a response in every cell in the body, allowing for increased energy metabolism. It can contribute to the activation of various genes. Athletes, healthy people, and sick people can all benefit from hypoxia.

[0003] The beneficial effects of high-altitude training have long been known. However, until a few years ago, it was not fully explained how a slight oxygen deprivation could lead to improved physical performance. The observed increase in red blood cells was not sufficient to explain the changes occurring within the body. A breakthrough in understanding came with the discovery of the hypoxia-inducible factor HIF-1α, which helped explain the comprehensive effects of high-altitude training. The abbreviation HIF stands for hypoxia-inducible factor. The reason for this terminology is that it is an oxygen sensor that is activated when oxygen is deficient within the body's cells. The oxygen sensor controls one of the most important processes in the body for survival: the adaptation of cells, tissues, and organs to oxygen deprivation. At the same time, it also acts as a signal to promote self-repair within the body.

[0004] The best-known beneficial effect of HIF is the synthesis of erythropoietin (EPO) in the kidney and liver. This synthesis played a role in explaining changes in the cardiovascular, respiratory, and hematologic systems prior to the discovery of HIF. It is now clear that the performance improvements are more comprehensive. Endothelial cells in the intima respond to the effects of hypoxia with increased synthesis of nitric oxide (NO). This gas plays a crucial role in vasodilation. NO leaves the endothelium and exerts a relaxing effect on smooth muscle cells in the surrounding tissue. In the intima-media tunica itself, NO prevents platelet adhesion and aggregation. In this context, it is also interesting to note that endothelial cells produce the angiogenic factor VEGF under the influence of hypoxia. This formation results in the formation of new capillaries in the context of hypoxic therapy. These new vessels are frequently present in damaged tissue or in areas of tissue with poor blood flow.

[0005] All known devices for performing hypoxic training are based on pendulum breathing and have at least one breathing reservoir into which a certain amount of ambient air is introduced at the beginning of each diagnostic, training, or therapy session. When a user connected to this reservoir inhales and exhales from the reservoir, the oxygen in the reservoir is consumed, producing an oxygen-deficient, oxygen-containing gas mixture in the reservoir. This mixture is purified from excess carbon dioxide, and the remaining oxygen content is measured at least periodically during each session.

[0006] WO2012 / 005712 presents a breathing apparatus for using a hypoxic gas mixture, the apparatus comprising a support frame, a breathing reservoir with an inhalation valve, a first sensor for the oxygen content and an absorber for CO2 and HO, a controllable compressor connected to the breathing reservoir via a puff valve, a chamber for sampling and accumulating aliquots of the gas mixture with a second sensor for the oxygen content, a controllable regulating valve and a controllable ejector, a user attachment, an inhalation line with a controllable center valve and a first flow meter for measuring the inhalation rate, a main exhalation line with a T-fitting and a first air blower connecting the attachment to the reservoir, an additional exhalation line with a second flow meter for measuring the sample aliquot volume and a second air blower connecting the connection to the chamber, an additional sensor complex and a control unit.

[0007] The device presented here is very complex in design and therefore very expensive to purchase, and its use is particularly complex for individual users and therefore must be carried out under the supervision of a specialist.

[0008] It is therefore an object of the present invention to provide a hypoxic device for administering hypoxic therapy and / or hypoxic training that is efficient, cost-effective, and allows an individual user to administer hypoxic training in a safe manner without professional supervision.It is a further object of the present invention to provide a method for administering hypoxic training that allows for the safe and at the same time efficient administration of hypoxic training for an individual user, even without professional supervision.

[0009] The above mentioned object is achieved by means of a hypoxic device for performing hypoxic therapy and / or hypoxic training according to claim 1. Further advantageous configurations of the invention are described in the dependent claims.

[0010] A device for performing hypoxic therapy and / or hypoxic training according to the present invention includes a gas reservoir. The gas reservoir is an air or gas reservoir containing a mixed gas for performing hypoxic therapy and / or hypoxic training. The hypoxic device further includes a gas supply device for performing hypoxic therapy and / or hypoxic training. The gas supply device is typically embodied as a breathing mask that a user wears over their breathing openings (mouth and nose) to perform hypoxic therapy and / or hypoxic training. The device for providing a hypoxic mixed gas further includes a supply line suitable and designed for conducting the mixed gas from the gas reservoir to the gas supply device, and / or an exhaust line suitable and designed for conducting the mixed gas from the gas supply device to the gas reservoir. The supply line and / or exhaust line are typically embodied as flexible hoses that gas-tightly connect the gas supply device to the gas reservoir. The hypoxic device for performing hypoxic therapy and / or hypoxic training further includes a CO sensor disposed in the supply line and / or exhaust line.

[0011] The hypoxia device of the present invention is a so-called pendulum rebreather, which means that the same air is repeatedly inhaled and exhaled. Normal breathing air contains 21% oxygen. With each breath, approximately 4% of the oxygen is removed from the inhaled air and replaced by an equivalent amount of exhaled carbon dioxide (CO2). In principle, a certain amount of air can be "breathed" several times in this way until its oxygen content is depleted, but the exhaled carbon dioxide accumulates in the air in the breathing circuit. Furthermore, too much carbon dioxide in the inhaled air poses physiological risks. A concentration of 5% or more can lead to loss of consciousness, and a prolonged concentration of 8% or more can lead to death.

[0012] For this purpose, the hypoxic device according to the invention has a CO2 sensor arranged in the supply line or the discharge line of the breathing circuit. The CO2 content of the breathing air can preferably be measured continuously using the CO2 sensor. The CO2 sensor can, for example, have an optical and / or acoustic display and / or be connected to an optical and / or acoustic display that emits a warning signal when the CO2 content of the breathing air in the breathing circuit detected by the CO2 sensor reaches a value that is dangerous for the user.

[0013] Additionally, the hypoxic device according to the present invention may include a CO2 absorber, which is also placed in the supply line and / or the exhaust line. The CO2 absorber is typically a solid mixture of calcium hydroxide and sodium hydroxide (so-called soda lime). During hypoxic therapy and / or hypoxic training, air flows through the soda lime, where carbon dioxide first combines with the sodium hydroxide and is then regenerated by the calcium hydroxide, also known as slaked lime, contained therein. A CO2 sensor also monitors the function of the CO2 absorber.

[0014] In an optional embodiment of the present invention, the hypoxic device is designed as a closed circuit, where it is important to monitor the gas status, and therefore the CO2 status, especially in closed circuits.

[0015] In a further development of the invention, the CO2 content of the gas supplied by the gas supply device can be monitored by means of a CO2 sensor. Preferably, the CO2 content of the air inhaled and exhaled by the user through the gas supply device can be detected continuously.

[0016] In a further embodiment of the invention, the hypoxic device comprises a threshold monitoring unit having a threshold value for the CO content of the gas supplied via the gas supply device, and if the CO content determined by the CO sensor exceeds the threshold value, a corresponding signal is issued and / or gas release by the gas supply device is stopped.

[0017] In a further embodiment of the invention, the threshold monitoring unit comprises a control unit, the threshold monitoring unit may be controlled using the control unit, the control unit comprising a processor and a suitable application.

[0018] In a further development of the invention, the control unit is provided with a storage unit, which has an application for controlling the threshold monitoring unit. In a further embodiment of the invention, a threshold value for the maximum CO2 concentration is stored in the storage unit.

[0019] In an advantageous embodiment of the present invention, the CO2 concentration determined by the CO2 sensor can be monitored by a threshold monitoring unit for exceedance of a threshold CO2 concentration. In particular, the threshold monitoring unit compares the determined CO2 concentration with a CO2 concentration threshold. If the determined CO2 concentration exceeds a threshold stored in the storage unit, an optical and / or acoustic warning signal can be emitted by the threshold monitoring unit, for example, to warn a user of the hypoxia device. Alternatively or additionally, the threshold monitoring unit can interrupt the gas supply to the gas supply device.

[0020] In a further embodiment of the invention, the hypoxic device comprises an automatic shut-off device, which is also preferably controlled by the control unit of the threshold monitoring unit, and which is automated in such a way that the shut-off device is activated without user intervention.

[0021] In a further advantageous embodiment of the present invention, the gas supply to the gas supply device can be interrupted by a shut-off device. If the determined CO concentration exceeds a threshold value stored in the storage unit, the shut-off device interrupts the gas supply to the gas supply device in such a way that the user can no longer perform hypoxic training and must disconnect the gas supply device from the breathing port. In a further embodiment of the present invention, the shut-off device has a shut-off valve.

[0022] In an advantageous embodiment of the present invention, after activation of the shutoff device, CO2 is exhausted or removed from the breathing circuit by means of the inlet valve and / or outlet valve. Furthermore, the inlet valve and / or outlet valve can be used to introduce air and / or oxygen into the breathing circuit. After the gas is released or introduced, the shutoff device is reset. Optionally, the CO2 sensor is coupled to a two-point controller that controls the inlet and outlet valves. When a first threshold is reached, the inlet or outlet valve is opened to introduce air and / or oxygen or remove CO2. When a second threshold is reached, the inlet or outlet valve is closed again. The first threshold of CO2 content is a CO2 concentration higher than the second threshold. Optionally, a third threshold may be provided that activates the shutoff device. The third threshold of CO2 concentration is higher than the first and second thresholds.

[0023] In a further advantageous embodiment of the present invention, the hypoxic device has a CO2 absorber that absorbs CO2 from exhaled air. In this embodiment, a CO2 sensor is positioned adjacent to the CO2 absorber and monitors its function. If the CO2 sensor detects a decrease in the function of the CO2 absorber, a shut-off device is activated. In an optional embodiment of the present invention, the function of the CO2 absorber is monitored by two CO2 sensors. A first CO2 sensor is located in front of the CO2 absorber, and a second CO2 sensor is located behind the CO2 absorber. During monitoring, measurements determined by the CO2 sensors are compared.

[0024] The above-mentioned object is further achieved by means of a method according to the invention for performing hypoxic training.Further advantageous embodiments of the invention are also described in the dependent claims.

[0025] The method according to the invention for performing hypoxic training comprises two method steps: In a first method step, a hypoxic gas mixture is provided, which has a reduced oxygen content, in particular compared to conventional breathing air.

[0026] In a second step, a measurement signal is detected by a CO2 sensor, which preferably continuously measures the CO2 content of the gas mixture and generates a measurement signal that is evaluated by a suitable control unit connected to the CO2 sensor. In particular, the control unit preferably continuously monitors the CO2 content of the gas mixture.

[0027] In a further development of the invention, measurement signals are recorded in the gas reservoir, supply line and / or discharge line of the hypoxic device. The gas reservoir, supply line and discharge line are connected so that the gas mixture therein has the same composition. Depending on the design and size of the hypoxic device and the spatial conditions of the location of the hypoxic device, CO2 sensors can be placed in the gas reservoir, supply line and / or discharge line to generate the measurement signals.

[0028] In an advantageous embodiment of the invention, the CO2 concentration is determined from the measured measurement signal. The CO2 sensor is connected to a control unit having a processor and a suitable application.

[0029] In a further development of the invention, a threshold value is read from the storage unit, which determines the maximum CO2 concentration of the breathing gas at which the user can still perform hypoxic training.

[0030] In an advantageous embodiment of the invention, a threshold value is compared with the determined CO concentration. If the determined CO concentration exceeds the threshold value stored in the storage unit, an optical and / or acoustic warning signal can be emitted by the threshold monitoring unit, for example, to warn a user of the hypoxia device. Alternatively or additionally, the threshold monitoring unit can interrupt the gas supply to the gas supply device.

[0031] In a further embodiment of the invention, a shut-off device is activated when the determined CO concentration exceeds a limit value. The shut-off device is also preferably controlled by a control unit of the threshold monitoring unit. The shut-off device is automated in such a way that the shut-off device is activated without user intervention.

[0032] In a further advantageous development of the invention, the gas supply to the gas supply device can be interrupted by the shut-off device when activated. If the determined CO concentration exceeds a threshold value stored in the storage unit, the shut-off device interrupts the gas supply to the gas supply device in such a way that the user can no longer perform hypoxic training and must disconnect the gas supply device from the breathing port. In a further embodiment of the invention, the shut-off device has a shut-off valve.

[0033] In a further development of the invention, the threshold value is a limit value, the threshold value or limit value indicating the maximum CO2 concentration of the breathing gas at which the user can still perform hypoxic training.

[0034] In an advantageous embodiment of the invention, the hypoxic device comprises an inlet valve and / or an outlet valve, which can be used to vent or remove CO2 from the breathing circuit, and which can also be used to introduce air and / or oxygen into the breathing circuit.

[0035] Optionally, the CO2 sensor is coupled to a two-point controller capable of controlling the inlet and outlet valves. When a first threshold is reached, the inlet or outlet valve can be opened to introduce air and / or oxygen or to remove CO2. When a second threshold is reached, the inlet or outlet valve can be closed again. The first threshold of CO2 content is a CO2 concentration higher than the second threshold. Optionally, a third threshold may be provided, and when this third threshold is reached, a shut-off device can be activated. The third threshold of CO2 concentration is higher than the first and second thresholds.

[0036] In a further advantageous embodiment of the present invention, the hypoxic device has a CO2 absorber that absorbs CO2 from exhaled air. In this embodiment, a CO2 sensor is positioned adjacent to the CO2 absorber to monitor its function. If the CO2 sensor detects a decrease in the function of the CO2 absorber, a shut-off device can be activated. In an optional embodiment of the present invention, the operation of the CO2 absorber is monitored by two CO2 sensors. A first CO2 sensor is located in front of the CO2 absorber, and a second CO2 sensor is located behind the CO2 absorber. During monitoring, measurements determined by the CO2 sensors are compared.

DETAILED DESCRIPTION OF THE INVENTION

[0039] 1 shows a diagram of a hypoxic device 1 for performing hypoxic therapy and / or hypoxic training. The hypoxic device 1 has a gas supply device 20, which is embodied as a breathing mask and is worn by a user P over their breathing openings (mouth and nose) during hypoxic therapy and / or hypoxic training.

[0040] The hypoxic device 1 also comprises a gas reservoir 10. The gas reservoir 10 and the gas supply device 20 are connected to each other in an airtight manner via a flexible gas line 30. During hypoxic therapy and / or hypoxic training, the user P wears the gas supply device 20 and inhales and exhales the gas contained in the gas reservoir 10 several times.

[0041] To monitor the CO2 content of the respiratory gas, the hypoxic device 1 has a CO2 sensor S that can be placed at different locations on the hypoxic device 1. The CO2 sensor S can be placed on the gas line 30 (Fig. 1a), in the gas reservoir 10 (Fig. 1b), or in the gas delivery device 20 (Fig. 1d).

[0042] In a further exemplary embodiment (FIG. 1c), the gas line 30 may be divided into a supply line 40 and an exhaust line 50. The supply line 40 and the exhaust line 50 each have a one-way valve V, which allows circulation of breathing gas through the hypoxic device 1 in only one direction. In this embodiment, the CO2 sensor S is located in the exhaust line 50. However, it is also possible for the CO2 sensor S to be located in the gas reservoir 10 or in the gas supply device 20.

[0043] 1 is a diagram showing a hypoxic device 1 for performing hypoxic therapy and / or hypoxic training. The hypoxic device 1 has a gas supply device 20, which is embodied as a breathing mask and is worn by a user P over the breathing openings (mouth and nose) during hypoxic therapy and / or hypoxic training.

[0044] The hypoxic device 1 also comprises a gas reservoir 10. The gas reservoir 10 and the gas supply device 20 are connected to each other in an airtight manner via a flexible gas line 30. During hypoxic therapy and / or hypoxic training, the user P wears the gas supply device 20 and inhales and exhales the gas contained in the gas reservoir 10 several times.

[0045] To monitor the CO2 content of the respiratory gas, the hypoxic device 1 has a CO2 sensor S that can be placed at different locations in the hypoxic device 1. The CO2 sensor S can be placed on the gas line 30 (Fig. 1a), in the gas reservoir 10 (Fig. 1b), or in the gas supply device 20 (Fig. 1d). The CO2 sensor S generates a measurement signal from which the CO2 content of the respiratory gas in the hypoxic device 1 can be determined.

[0046] In a further exemplary embodiment (FIG. 1c), the gas line 30 may be divided into a supply line 40 and an exhaust line 50. The supply line 40 and the exhaust line 50 each have a one-way valve V, which allows circulation of breathing gas through the hypoxic device 1 in only one direction. In this embodiment, the CO2 sensor S is located in the exhaust line 50. However, it is also possible for the CO2 sensor S to be located in the gas reservoir 10 or in the gas supply device 20.

[0047] A variant of the hypoxic device 1 according to the invention is shown in Figure 2. In this exemplary embodiment, as in the preceding exemplary embodiment (see Figure 1c), the gas line 30 has separate supply and discharge lines 40 and 50, which also each have a one-way valve V. A CO2 sensor S is arranged in the discharge line 50 and is connected to a control unit C. By means of the control unit C, the CO2 content of the respiratory gas in the hypoxic device 1 can be determined from the measurement signal of the CO2 sensor S.

[0048] 3 shows an advantageous exemplary embodiment of a hypoxia device 1 according to the present invention. The gas line 30 also has separate supply and discharge lines 40 and 50, each with a one-way valve V. A CO sensor S is arranged in the discharge line 50 and connected to the control unit C. Furthermore, a shut-off device A is arranged in the supply line 40, which is also connected to the control unit C. The gas supply to the gas supply device 20 can be interrupted by means of the shut-off device A.

[0049] 4 shows a preferred exemplary embodiment of a hypoxic device 1 according to the present invention. The gas line 30 also has separate supply and discharge lines 40 and 50, each with a one-way valve V. The hypoxic device 1 has a threshold monitoring unit 100, in which a CO sensor S, a control unit C, a shut-off device A, and a memory unit M connected to the control unit C are arranged together. A threshold value for the maximum CO concentration of the respiratory gas is stored in the memory unit.

[0050] To perform hypoxic training, the user P places the gas supply device 20 over the breathing port and repeatedly inhales and exhales the same breathing gas. During hypoxic training, the threshold monitoring unit 100 monitors the CO2 concentration of the breathing gas by detecting a measurement signal of the breathing gas in the discharge line 50 using the CO2 sensor S. The measurement signal is sent to the control unit C, which calculates the CO2 concentration of the breathing gas using an appropriate application based on the measurement signal received from the CO2 sensor S. The control unit C compares the determined CO2 concentration of the breathing gas with a threshold value stored in the memory unit M, which is also a limit value for the CO2 concentration of the breathing gas. If the determined CO2 concentration of the breathing gas exceeds the threshold value, the control unit C sends a control signal to the cutoff device A, which interrupts the gas supply to the gas supply device 20. The cutoff device A closes a shutoff valve disposed within the cutoff device A so that the supply line 40 is shut off. The threshold value for the CO2 concentration of the breathing gas is 3% of the breathing gas in all exemplary embodiments.

[0051] In this embodiment, the cutoff device A has a cutoff valve. However, the cutoff device A can alternatively or additionally be connected to one or preferably both one-way valves V, which interrupt the gas supply to the gas supply device 20 when a determined threshold CO concentration of the respiratory gas is exceeded. If the determined CO concentration is below the threshold, the cutoff device A is not activated and the user P can continue with the hypoxic training.

[0052] For this purpose, the hypoxic device 1 also comprises a measuring device that permanently monitors the health status of the user P during hypoxic treatment and / or hypoxic training. In particular, a pulse oximeter is used to monitor the heart rate and the oxygen content in the blood. The measuring device is connected to a control unit that issues an alarm signal in the event of a complication, e.g., a drop in the oxygen level in the user's blood, so that the hypoxic treatment and / or hypoxic training is immediately stopped.

[0053] In a further exemplary embodiment of the present invention, the hypoxic device has an inlet valve and / or an outlet valve. The inlet valve and / or the outlet valve can be used to vent or remove CO2 from the breathing circuit. Additionally, the inlet valve and / or the outlet valve can be used to introduce air and / or oxygen into the breathing circuit.

[0054] In any development of the preceding embodiment, the CO2 sensor is coupled to a two-point controller capable of controlling an inlet valve or an outlet valve. When a first threshold value is reached, the inlet valve or outlet valve is opened to introduce air and / or oxygen or remove CO2. When a second threshold value is reached, the inlet valve or outlet valve can be closed again. The first threshold value of the CO2 content is a CO2 concentration higher than the second threshold value. Optionally, a third threshold value may be provided, and when this third threshold value is reached, a shut-off device can be activated. The third threshold value of the CO2 concentration is higher than the first and second threshold values.

[0055] In a further embodiment, the hypoxic device comprises a CO2 absorber capable of absorbing CO2 from exhaled air. In this embodiment, a CO2 sensor is positioned adjacent to the CO2 absorber to monitor its function. If the CO2 sensor detects a decrease in the function of the CO2 absorber, a shutoff device can be activated. In an optional embodiment of the invention, the function of the CO2 absorber is monitored by two CO2 sensors. A first CO2 sensor is located in front of the CO2 absorber and a second CO2 sensor is located behind the CO2 absorber. During monitoring, measurements determined by the CO2 sensors are compared.
